Description

Technical Field

[0001] The utility model relates to the technical field of leech egg and cocoon hatching, in particular to a leech egg and cocoon hatching device. Background Art

[0002] Leeches, also known as leeches, contain natural hirudin, the strongest natural thrombin inhibitor discovered. It significantly dilates blood vessels, reduces blood viscosity, and increases circulation. It is clinically effective in treating conditions such as hypertension, stroke, coronary heart disease, and arterial thrombosis. Leeches are also used in microsurgery, where they absorb blood from wounds, promoting circulation and wound healing.

[0003] Leeches need to burrow into the soil when laying eggs. After laying eggs, in order to conveniently pick out leeches and egg cocoons from the soil, breeders need to use tools such as wooden sticks, branches or shovels to dig out pieces of soil, and then search for leeches and leech egg cocoons. However, because the force applied by the shovel or wooden stick is uneven and the shovel point is not accurately controlled, the position of the leeches and egg cocoons in the soil is unknown. Hard tools can easily damage the egg cocoons and leeches during the digging process, resulting in a low replenishment rate. For this reason, we propose a leech egg cocoon incubation device.

The small holes 21 are used for the larvae in the egg cocoon to directly enter the water after breaking out of the cocoon. The leech egg cocoon is in the shape of an ellipsoid, and the longest outer diameter and the shortest outer diameter of the leech egg cocoon are about 2-3 cm. The radius of the small hole 21 is set to be smaller than the minimum radius of the egg cocoon to ensure that the egg cocoon will not be broken from the small hole 2. 1 falls off, an egg-laying box 3 is provided on one side of the incubator 1, a rope rack 4 is provided in the egg-laying box 3, the rope rack 4 is fixedly connected with a rope net 5, the rope diameter of the rope net 5 is 2 cm, the grid of the rope net 5 is square, and the grid side length is greater than the maximum outer diameter of the egg cocoon, so that the rope net 5 can ensure the effect of breaking the soil block without causing shear force on the egg cocoon, thereby destroying the egg cocoon, the rope rack 4 is also rotatably connected to the chain rack 6, the rope rack 4 is also fixedly connected to the bracket 7, and the bracket 7 is rotatably connected to the connecting The connecting piece 8 is rotatably connected to the slider 9, the slider 9 is rotatably connected to the connecting rod 10, the other end of the connecting rod 10 is rotatably connected to the bracket 7, the bracket 7 is also rotatably connected to the fixing rod 17, the fixing rod 17 is rotatably connected to the slide rail 11, the slider 9 is fixedly connected to the pulley mechanism 12, the pulley mechanism 12 includes a pulley 121 and a limiting wheel 122, the pulley 121 and the limiting wheel 122 are rotatably connected, the pulley 121 and the limiting wheel 122 are used to reduce friction, the pulley 121 The limiting wheel 122 is in rolling contact with the slide rail 11, the slide rail 11 is fixedly mounted on the inner wall of the egg-laying box 3, the rope net 5 is fixedly connected to the lifting frame 13, the lifting frame 13, the rope frame 4 and the chain frame 6 jointly fix the rope head part of the rope net 5, the lifting frame 13 and the chain frame 6 are rotatably connected, and a fixed pulley 14 is also provided on one side of the egg-laying box 3. A motor 15 is fixedly provided on one side of the fixed pulley 14, and the lifting frame 13 is fixedly connected to the motor 15 through a suspension rope 16 wrapped around the fixed pulley 14.

[0022] Working principle: Cover the bottom of the egg-laying box 3 surrounded by the chain frame 6, the lifting frame 13 and the rope frame 4 with a layer of sterilized and de-sanded soil. The soil height must be guaranteed to completely cover the rope net. Then place the leech mother into the egg-laying box 3 and use wet gauze to block the light. After waiting for 10 days, take out the gauze, start the motor 15 to wind the suspension rope 16 through the fixed pulley 14 and then pull the lifting frame 13. Then the lifting frame 13 pulls the rope net 5 and the chain frame toward the fixed pulley 14. During this period, the lifting and lowering of each chain section of the chain frame 6 can be controlled by controlling the switch of the motor 15, thereby lifting the rope net 5 layer by layer in an orderly manner. The rope net 5 will gradually destroy the soil layer during the lifting process to break the soil blocks into appropriate sizes and ensure the integrity of the egg cocoons. Then the breeding workers can collect the turned soil layer in an orderly manner according to the number of chain sections of the rope net 5 and the chain frame 6. The exposed egg cocoons and leeches can be removed, which not only reduces the damage rate of the egg cocoons but also improves the digging speed of the leeches and egg cocoons. When the rope net 5 is lifted to a certain angle, the chain frame 6 will drive the rope frame 4 and the bracket 7 thereon to lift to complete the crushing work of the last soil area. The linkage mechanism composed of the connecting piece 8, the slider 9, the connecting rod 10 and the fixed rod 17 will lift the rope frame 4 from the bottom of the egg-laying box 3 by a distance, instead of limiting the rope frame to rotate at the bottom of the egg-laying box 3. This is conducive to the collection of leeches and egg cocoons in the last piece of soil area. In addition, the pulley 121 and the limiting wheel 122 roll in the slide rail 11 respectively to reduce friction. All the egg cocoons collected from the egg-laying box 3 are placed on the hatching plate 2 and covered with gauze. After the larvae in the egg cocoons hatch, they can directly drill out from the several small holes 21 and enter the water under the attraction of the water source inside the incubator 1.
